Specification of Letters Patel 1E Patented July 1, 1919..

Application filed August 15,1916. Serial No. 115,063.

Be it known that I, Gnome B. JACKSON, a .citizen of the United States,residing in Guelph, Provinceof ()ntario, Dominion of Canada, haveinvented certain Improvements in Torpedo-Making Machines, of

which the following is a specification.

The object of my invention is to provide a machine for makin torpedoesof substantially the character illustrated in my Patent No. 1,182,767,dated May 9, 1916, and in my pending application for patent filedJanuary 25, 1911, Serial No. 604,635, such torpedoes consisting of atube of ductile metal containing a charge of detonating material, withthe ends of said tube, integral therewith, folded, crimped or otherwiseshaped into retaining members whereby the torpedo may be secured to thehead of a rail.

Preferably the ends of the tube are ,lon gitudinally corrugated orfolded in order that a certain amount of strength maybe ill added to themetal comprising the same, and the apparatus constituting the subject ofmy invention is designed to receive the tubes of ductile metal, preparethe same for the reception of the charge, position the charge therein,fold or crease the ends of the tube, compresssaid ends after the foldshave been placed therein, and then to fold said rail-engaging straps orends a ainst the central portion of the torpedo, w 'ich may then bedischarged from the machine in finished form, ready for use. v

These and other features of my invention are more fully describedhereinafter, reference being had to the accompanying drawings, in which!Figure 1, is a plan view of one form of torpedo-making machine withinthe scope of my invention. f

Fig. 5, is a sectional elevation illustrating a modified constructionwithin the scopevo'f my invention. l

Fig. 6, is a plan view of a portion of the structure shown in Fig. 5.

Fig. 7 is a cross sectlonal view on the line' Figs, 8, 9, 1o, 11, 12,1e, 14 and 15, are" steps performed by the machine in developing a tubeof ductile metal into a finished torpedo.

In my improved machine, the ductile tubes a, usually of lead andpreferably seamless, are placed in a trough 1, shown by broken lines inFig. 1, and in elevation in Fig. 2, from which they are picked up bypocket members 2 of an endless chain 3, adapted to sprocket wheels 4 and5 carried by shafts 6 and 7. These shafts are suitably journaled inbearings 6.and 7 carried by the frame 8 of the machine, and said shaft 6may be a driven shaft carrying a ratchet wheel 9, to which motion may beimparted by a pawl 9", pivotally mounted on the end of an arm 9"journaled on the shaft 6. This motion is in the nature of a step-by-stepmovement; it being necessary to provide intervals of timein operatingthe chain for certain operations or work upon the torpedo tubes carriedthereby. For this purpose, the arm 9 carrying the, pawl is connected bya rod 10 to a bell crank lever 11 pivoted to the frame 8 of the machineat 12, and having its opposite end, preferably provided 'with' a roller13 in operative engagement with a chine and arranged to reciprocatelaterally with respect to. the chain 3 and the tubes carriedthereby areframes 20 and 21; the

ends of the same being adapted to guidewa s at the ends of the frame,and they may e provided with rollers 22 to facilitate their movement.These frames carry suitable members for operation upon the tubes carriedby the chain, providing for the insertion of charges to successive tubesand the preparation of the tube ends for their finally folded or crimpedcondition.

The frames 20 and 21 are provided with racks 25 with which segmentaltoothed members 26 engage; said members being journaled on shafts 27mounted in brackets 28 hung from cross-bars 29 carried by the frame ofthe machine. These members 26 have arms 30 connected by links 31 to arms32 on a rock shaft 33 suitably jonrnaled in bearings 34 carried by theframe 8. The rock shaft 33 is provided with an arm 35 in operativeengagement with a cam groove 36, in a disk 37 mounted on the drivingshaft 16, and said groove may be so constructed that the inward motionof the frames is relatively slower than the outward motion, in orderthat sufficient time for movement of the chain between said lateralmovement of the frames is assured.

It will be understood, of course, that the tubes are fed successively tothe pocket members of the chain and that each tube passes through aseries of operations necessary to prepare it for the charge, introducethe charge therein, and then finish the tube and deliver a completetorpedo.

For the description of these several steps, a single tube will beconsidered; it being understood that for each movement of the frames ZOand 21 all of the operations are being performed upon independent tubesin regular sequence. For clearness of description, I will refer to theoperations carried out upon a single tube in its passage through themachine.

At the first stop or station of a tube carried by one of the pockets 2of the chain 3 and indicated at A, squared forming members 40 carried bysaid frames 20 and 21 and movable by the latter at right angles to themovement of the chain, are introduced into opposite ends of a tube ahalted by the chain at said position A. These members 40111-9. squaredand have the effect of changing the shape of the tube at the ends of thesame from a relatively cylindrical contour to a rectangular or squaredcontour, as shown at b in Fig. 9, for a purpose hereinafter described.In addition, it is desirable to slightly spread the ends of the tubesforproper cooperation with certain of the forming members, hereinafterdescribed, and for this purpose the members 40 may be provided withshort blades 41 set at such position with relation to the tube that whensaid frames 20 and 21 have been moved the full distance toward the chainwith said formers 40 within the tube ends, that said knives will havethe effect of slitting for a short distance the squared ends of the tubeat the corners of the same, as indicated at 0, in Fig. 9.

After this operation has been effected, the

frames 20 and 21 are retracted, carrying the.

forming members 40 out of the tubes. The chain 2 is now advanced,bringing the partially formed tube to the second step or station,indicated at B, and the laterally movable frames 21 are again operatedtoward the chain, and a pusher member 42 introduces one of thedetonating charges from its pocket 17 into the squared end of the tube;the pocket communicating with a delivery channel 43, in the rail 38 inregistry with the end of the tube. This pusher 42 is of a lengthsutlicient to bring the detonating charge well within the tube, and suchpusher 42 as well as a eomplemental pusher 42 at the opposite side ofthe machine and carried by the frame 21, but having nothing to do withthe' positioning of the detonating charge, are preferably of suchcontour and size as to engage the ends of the tube into which they areintroduced and change the shape of the same from one in which thevertical dimension is the greatest to one in which the horizontaldimension is the greatest; the reshaped ends being shown at (I, Fig. 10.

The frames 20 and 21 are again retracted, withdrawing. the members 42and 42, and the chain is advanced to the third station or position C. Atthis point, a plurality of wires 45, suitably carried by the frames 20and 21 and preferably three in number, with their longitudinal axes inthe same horizontal plane. are introduced into the ends of the tube;said wires forming in effect a corrugated mandrel. Simultaneously withthe introduction of these wire mandrels. blades 46 and 46 pivoted at, 47and 47" to the rails 38 and 38 are brought in contact with the tubeabove and below the same: such blades engaging the tube between thewires of the mandrel. and this action will have the effect of crimpingor corrugating the walls of the tube at the ends of the same in linewith the longitudinal axis of the tube. as shown at. in Fig. 11. Inaddition, the wire mandrels are of such length as to properly positionthe charge of detonating material with respect to the tube, in thecenter of the same. Cori-ligation or crimping of the tube ends by theblades takes place as the mandrel nears the end of its inward movement,and after such corrugation has taken place, the wire mandrels arewithdrawn.

The blades 46 and 46 which compress the walls of the tube ends betweenthe spaces of the rods or wires forming the corrugated mandrels are moreclearly illustrated in Fig. 4; the same being a sectional elevation ofthe machine on the line IVIV, Fig. 1. It will be noted in such view thatthe blades 46 and 46 are pivotally connected at 47 and 47 to the rails38 and 38 above and below the table over which the chain passes, and areconnected at 48 by links or rods 49 with the sliding frames20 and 21;such links being attached thereto at 50, so that as said frames 20 and21 are moved toward the chain, the blades will be swun on their pivotalconnections simultaneous y with the 1,308,361 will introduction of themandrels, around or over the rods of which the Walls of the tube endswill be shaped by said blades.

The chain is then moved to bring the tube to the next station D, andlaterally movable compressing blades 52 and 52 operatively connected tothe frames 20 and 21, are

brought against the tube ends from opposite sides of the same, whichaction has the elfect of flattening down the corrugated portions formedin said tube ends,a.fas indicated" at f in Fig. 12. These blades 52 and52 are pivoted to the rails 38 and 38 at 53, and are connected to rods54 and 54 at the points 55; said rods being connected at the points 56to the frames 20 and 21, so that inward movement of said frames willclose the blades, and outward movement of the same willopen the blades.These blades are provided withv flanges 57 and 57 so that the metal atthe ends of the tubes will be held from spreading vertically as it iscompressed laterally. I

After the frames 20 and 21 have been retracted, opening the blades tothe position shown in Fig. 1, the chain is then moved to bring the tubeto the next station E, and.

on its way it passes a roller 60 mounted at the endof an arm or rod 61carried by and movable with the frame 20, and which is maintained in arelatively fixed position with respect to the chain when the frames arein their retracted position; such roller 60 being so disposed that itwill engage one of the folded ends of the loaded torpedo tube and movethe same into a position in line with the chain, as shown at g, in Fig.

13, and then when the frames 20 and .21 are operated toward the chain,the roller will be carried by its supporting arm 61 and 1 will movethefolded end of the torpedo tube against the central portion of the samewhich has received the charge, as shown at h, in Fi 14.

The rames are then chain moved to brin the torpedo to the next stationor stop F, w ere a similar roller 60, carried-by a rod or arm 61" hasengaged and bent the folded end of the tube in line with the chain,'asshown at 9', Fig. 14, so that upon the next inward, movement of theframes 20 and 2 1, such end of the tube 'will .be folded over the firstend, in the manner described with reference to the same, and as I shownat h, 15. The chain is again moved after the frames 20 and 21 have beenretracted, and upon this movement, or the next movement of the same, thecompleted torpedo with its folded ends bent back upon the same, as shownin Fig. 15, is discharged from the pocket of the chain. 7

It will be understood from they foregoing description, detailingtheseveral operations retracted, and theupon. a single tube, that thesame operations are being carried out upon similar tubes successivelyfed to the pockets of the chain, and that each operation referred totakes place in connection with the ends of the tubes at the respectivestations or stopping points of the chain.

The pockets 2 of the chain 3 are preferably of theconstructionillustrated in F igs; 2 and 3, wherein they are represented as having asubstantially straight back Wall with a curved lip or front wallmaterially less in height than the back wall; said walls forming a seatfor the tubes as they are picked from the trough by the rear wall of thepocket passing through the notch formed in the delivery end of the same.

In some instances, it may be desirable to provide pockets for the tubesin which they may be clamped after the detonating charge has beenintroduced into the same, and for such purpose I may employ a structurehaving detalls such as are illustrated in Figs. 5, 6 and 7.

.In Fig. 6, which is a'fragmentary view, suflicient, however, toillustrate the modified construction, I have provided a pair of chains 3with a series of pockets 2, supported at their ends by the same, eachpocket having a front wall with a movable central section 62. Thesesections may be provided with depending portions 63 forming arms forengagement with a cam face 64 formed in the bed-plate so as to bemaintained in the open position, ready to receive a tube, until suchtube is in place; such depending portions being connected by springs 65with the links of the preceding pockets, so that when the cam face 64 ofthe table groove 64 is passed, the springs will cause the movableportions of the pockets to retract and grip the tubes carried thereby atthe center of the same.

In the arrangement illustrated in Fi 1, 2 and 3, I have shown the use ofa single chain for carrying the tube -receiving "pockets, while in themodified construction ner illustrated in Figs. 8 to 15, inclusive,

to form finished torpedoes. p

The ends of the first plungers 40 adapted to enter the torpedo tubes arepointed so that ingress to effect the desired shaping of the tubes,which is to square the ends of the same, is easy, and the knives 41carried by these plungers are set at such position that they ust engagethe ends of the tubes and slit the walls of the same at the cornersthereof. These tubes have their ends'shaped substantially rectangularly,with a width less than their height, and the flared .end is of materialadvantage in introducing the charge and the succeeding plungers ortools.

The charging member 42 has a greater width than height, and thecomplemental member 42 on the opposite side of the machine is of thesame shape; the ends of said plun ers being tapered so that they mayreadfiy enter the tube; one of the same pushing the charge in advancethereof, and both plungers acting upon the ends of the tubes to changetheir shape from a rectangular contour whoseheight is greater than itswidth, to a substantially rectangular contour in which the widthpf thetube ends is greater'than their height; preparing them for the receptionof the wire mandrels 45 at the next station of the chain.

The various movable parts of my improved torpedo making machine areactuated from the driving shaft 16, which may be actuated continuouslyin any usual or approved manner, (not shown).
